The company's non-GAAP earnings per share reached $1.76, significantly beating the Wall Street consensus of $1.40.

CEO Phil Brace commented on the outlook, stating, "In mobile, underlying demand trends remain solid, supported by healthy sell-through and new product launches. Looking ahead, we expect rising AI-driven data traffic to drive greater radio-frequency complexity."
